I don't care that the program tells you it's reading at XX . I've tested them and SEEN the blips of kr that the TQ app didn't show. I've also seen the blips of kr the AeroForce doesn't show with my tuner.
I have, with the Torque Pro developer. The slowest readings we have got has been 20 readings per second. According to Aeroforce's own website, that's the same speed as an Aeroforce.

The USB OBD2 adapter (OBDlink SX in my case) reads even faster, I typically see 40-50 reads per second.
